CG: I DON'T "GOT" TO ADMIT A SINGLE GOGDAMN THING.

CG: I GROW SICK AND TIRED OF YOUR PATHETIC BLUE TEXT.
CG: AND THIS IMPROMPTU SINGING IS GIVING ME A HEADACHE.
EB: Why don't you just go back and talk to me before I figured out you weren't such a bad guy?
CG YES! I WILL PSYCHOLOGICALLY DAMEGE YOU IN THE PAST SO THAT IN THE FUTURE, YOU WILL BE TOO RETARDED TO DEFEND YOURSELF! SEE YOU IN THE PAST EGBERT JOHN HUMAN!

EB: Okay Karkat, I look forward... er backward to it.

PEB: God damn, leave me alone you animal!
CG: THAT'S RIGHT YOU SOLID CHUNK OF HYPER COOLED SPACE PISS, I'M A PACK OF HUMAN WOLVES, AND YOU WERE THROWN TO ME LIKE A HELPLESS WRIGGLER!
PEB: I know I'm gonna regret asking this, but who threw me to you?
CG: YOUR FUTURE SELF IS THE ONE. IT'S YOU.
PEB: Yep, I'm regretting it.
CG: I WAS TALKING TO YOUR FUTURE SELF WHEN I FELT THE NEED FOR A MORE PSYCHOLOGICALLY WEAK VICTEM, AND HE SAID "OH WHY NOT TROLL MY YOUNGER SELF, HE IS A WEAK MINDED HUMAN AFTER ALL."
CG: THAT IS MY PATHETIC JOHN HUMAN VOICE DO YOU LIKE IT?
PEB: Yeah alright, I get it, what your saying is in the future I become a raging prick.
CG: WHAT
PEB: And I'm constantly spewing bullshit from my mouth like some anti toilet, but for bulls.

CG: HEY! SHUT UP DUMPASS YOU CAN'T TALK ABOUT YOUR FUTURE SELF LIKE THAT! HE'S MY FRIEND, AND HE'S TWICE THE MAN YOU ARE!
PEB: Okay, seriously you have issues dude.

CG: THEN LETS GET BACK!
